  1087 An iron preparation substantially lowers the quantity of palladium needed to catalyze a common reaction that forms C-C bonds. Most of today’s use of transition metal–catalyzed cross-coupling chemistry relies on expensive quantities of palladium (Pd). Here we report that nanoparticles formed from inexpensive FeCl3 that naturally contains parts-per-million (ppm) levels of Pd can catalyze Suzuki-Miyaura

  铁为痕量钯提供动力 钯 (Pd) 是化学催化的支柱。贵金属具有锻造碳-碳 (CC) 键的诀窍。汉达等人。现在报告说，当与铁混合在特定制剂中时，仅百万分之一的 Pd 就足以催化形成 CC 键的 Suzuki 偶联反应。表面活性剂的加入使反应在水中进行。该协议预示着在药物和农用化学品合成中保护 Pd 是个好兆头。科学，这个问题 p。1087 铁制剂显着降低了催化形成 CC 键的常见反应所需的钯量。今天大多数过渡金属催化交叉偶联化学的使用依赖于昂贵数量的钯 (Pd)。在这里，我们报告说，由天然含有百万分之一 (ppm) 水平 Pd 的廉价 FeCl3 形成的纳米粒子可以催化 Suzuki-Miyaura 反应，包括涉及极具挑战性的反应伙伴的情况。纳米胶束用于溶解反应物并将反应伙伴传递给 Fe-ppm Pd 催化剂，从而形成碳-碳键。新形成的催化剂可以在环境温度下分离和储存。含有表面活性剂和催化剂
